Wifi Bee is a xBee Pro socket compatible module.It integrates Microchip IEEE 802.11 Wi-Fi transceiver module MRF24WB0MA and 8bit AVR MCU ATmega328P. The smart and similar xBee Pro outlook makes it very easy to be integrated in your product. The ATmega328P could be directly programmed under the open source IDE Arduino when you plug it on to the UartSBee. The SPI pins on MCU are connected to the corresponding pins of MRF24WB0MA to communicate with each other, while some of the other pins (DIO, AD,PWM etc.) are brought out to the 20 pins of 2.0mm male pin headers.
